WILSON E. PORTER, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO NEW HAVEN CLOCK CO., OF NEW HAVEN, CONNECTICUT, A CORPORATION.

EIGHT-DAY ALARM-CLOCK.

Application filed July 2, 1915.

To all 10 hom it may concern Be it known that I, WILSON E. PORTER, a citizen of the United States, residing at New Haven, in thecounty of New Haven and State of Connecticut, have invented a new and useful Improvement in Eight-Day Alarm-Clocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of this application, and represent, in-

Figure 1 a view in front elevation of an eight-day alarm-clock constructed in accordance with my invention, the upper portion of the dial and case being broken away to show my improved combined alarm-stop and cut-out. Fig. 2 a detail view partly in elevation and partly in vertical section of my improved combined alarm-stop and cutout. Fig. 3 a view thereof in side elevation with the case in section. Fig. 4 a plan view thereof with the upper portion of the case broken away.

My invention relates to an improvement in that class of eight-day alarm clocks in which a continuous alarm is stopped by the manual operation of a push-button which is automatically released by the time-mechanism of the clock within the twenty-four hours next succeeding the sounding of an alarm, so that the clock is automatically restored to readiness for sounding an alarm. though manually operated for shutting off the alarm, the object of my present invention being to utilize the push-button in permanently cutting out the alarm.

With these ends in view, my invention consists in an eight-day alarm clock having a combined alarm-stop and cut-out constructed and arranged to co-act with one of the members of the alarm-mechanism, whatever the character of the alarm-mechanism may be.

In carrying out my invention as herein shown, I have applied it to an eight-day alarm-clock of the character shown and described in my prior Patent No. 1,156,552, dated October 12th, 1915, but I would have it understood that I do not limit the use of my improvement to a clock of such construction though it is especially well adapted thereto. As herein shown, I employ a permanent alarm-stop and alarm cut-out in Specification of Letters Patent.

Serial No. 37,725.

the form of a bow 2 corresponding to the ordinary bow of a watch, the ends of this bow being pivoted at opposite points in the circular head 3 of a hollow, externally threaded plug 4 which is screwed into a perforation formed in the top of the clockcase 5 which is at this point reinforced by a plate 6 applied to its inner face and also having a threaded perforation for the reception of the plug 4:. This plug forms a housing for a push-button 7 and plunger 8, the latter being furnished at its lower end with a conical button 9 engaging with the alarm-stop and let-off lever 10 of any suitable alarm-mechanism, such, for instance, as the alarm-mechanism shown and described in my prior patent above referred to, in which a corresponding lever is designated by the numeral 17. The push-button 7 is formed at its inner ,end with a concentric bore 11 threaded at its extreme inner end and receiving a threaded stem 12 upon the outer end of the plunger 8 which is actuated in being restored to its normal position by a helical spring 13 encircling it and located within the hollow plug 4, the lower end of the spring impinging against a. shoulder 14 at the lower end of the plug and the upper end of the spring impinging against the ex treme inner end of the push button 7. The said push-button 7 and plunger 8, as thus constructed. act as one piece. The said device viewed as an alarm-stop and cut-out device, is centrally located with respect to a bail-like handle 15 secured by headed posts 16 to the top of the clock-case 5 on either side of the center thereof.

When the alarm is sounded by the automatic release of the alarm-mechanism by the time-mechanism, in the customary manner, and as described in my said prior patent, the user of the clock may shut off the alarm by pushing in the push-button 7 for the engagement of the conical head 9 of the plunger 8 with the alarm-stop and letoff lever 10 which is disengaged from the head 9 automatically within the next succeeding twenty-four hours by the operation of the time-mechanism, whereby the lever is left free for the next sounding of the alarm, and the plunger is left in position to be again used for stopping the alarm. At this time, the bow 2 is swung to one side so as to permit the plunger 7 to be thrown to the limit of its outward movement by the helical spring 13. Normally, then, the how 2 Will be thrown down into position in Which it is shoivn by broken lines in Fig. 8, or into any deflected position in Which it Will clear the outer end of the push-button 7. In case,

sion of the helical spring 12. I am thus enabled by thesimple' provision of themechanism with -a bow 2 to provide a permanent cut-out for the alarm.

I claim: 1.. In an eight-day alarm clock, the combination with a clock-movement having an alarm-mechanism, of a clock-case, aspring-- actuated plunger mounted inthe clock-ease and coacting With a movable part of the said alarm-mechanism for restraining the same, and means also mounted in the clockease and (Jo-acting with the said plunger for manually locking the same in its alarmrestraining position.

In an eight-day alarm clock the combination with a movable member of the alarmmeohanism of the clock, of a springactuated plunger (Jo-acting with the said member, and a pivotal bow co-acting With the plunger for holding the same in its alarm-restraining position.

3. In an eight-day alarm clock the combination With a movable member of the alarm-mechanismof the clock, of a springactuated plunger co-acting with the said member and provided with a push-button, a plug mounted in the clock-case for the reception of the said plunger and push-button, and a bow pivotally mounted in the plug for co-a-otion 'With the push-button to retain the plunger in engagement with the said movable member against the tension'of the spring operating the plunger.
